15 oPERAtING REqUIREMENtS
The EKP-IV must be connected to a 10–35 V DC power source and the antenna requires a clear
view of the sky in order to operate.

Note
The cable that ends with wires is available as an optional part. Please contact your local C-MAP office for details.
15.1 ANtENNA ASSEMBLY & PLACEMENt
The antenna comes with a 5 meter cable with a SMB connector. The antenna is designed for use
inside the aircraft. It can be temporarily mounted on the aircraft's dashboard using the included
velcro strip.
The antenna must have a clear view of the sky in order to receive satellite signals. GPS uses "line
of sight" signals to locate and track satellites. If the signals are obstructed by dense objects such as
aluminum, steel or even heavy ice, the EKP-IV will not operate properly.
Signals may also be blocked by heated wind screens (fiberglass, plexiglass and other plastics are
nor-mally transparent to GPS signals).
The antenna can be mounted to any convenient surface that has a clear view of the sky. If you
find that the EKP-IV does not locate and track satellites quickly or consistently, move the antenna.
Moving the location of the antenna a few inches often provides a better view of the sky.
15.2 SECURING thE EKP-IV
The EKP-IV was designed to be mounted on your leg for operation. This will put the EKP-IV close at
hand and in an easily visible location without interfering with other equipment.
Use the elastic strap provided to secure the EKP-IV to your leg. Position the elastic strap around
your leg with the long looped strip on top. Fasten with the hook and loop closure at each end of
the strap. Hold the EKP-IV over the strap on your leg and lower into place.
Press down a little to be sure the strips are secure. If you prefer there are after market mounts
available for attachment to the yoke assembly or the seat rail tracks. Please contact your dealer for
more details on these items.
Note
Yoke mounts may not be appropriate for your aircraft. Use care to ensure that the EKP-IV does not obscure the
primary instruments.
